The S&P500 is going to continue this violent rally over the course of 3-5 days, upon which it is likely to consolidate into a very whipsaw'ish market environment for a few weeks, upon which it will see one of the most violent declines in the history of the stock market. That will be the next super long term bottom, and whilst a new bull market doesn't appear likely until 2012 onwards, we shouldn't see the 400 level breached again for the next 100 years.
